Komatsu EU Stage V

Komatsu consistently engages in the research, development, manufacture and improvement of diesel engines. In-house development and manufacturing capabilities are leveraged for key components, such as hydraulic devices and control systems, in order to reduce environmental impact and to improve fuel economy.

In-house development

 

 

Komatsu has begun supplying machinery in conformity with EU Stage V emission regulations to customers and new EU Stage V models will be announced when they are launched.

EU Stage V regulations

 

 

EU Stage V regulations apply to a wider range of engines. It places a limit both on the mass of emitted particle pollution (PM) and on the number of particles (PN) emitted by the engine.

Performance

 

 


Performance remains efficient and costs of ownership low.

KOMATSU EU STAGE V 

For machines in the 19kW – 560kW power level range to comply with these new PN requirements, a Komatsu Diesel Particulate Filter (KDPF) must be included in the engine’s aftertreatment system. With over 98 percent of KDPF regeneration performed passively, no action is required of the operator, with no interference to machine operation.
